The 1978 BMW R 100 S is a classic sport motorcycle from the late 1970s. Its 979cc engine delivers 70 horsepower at 7250 RPM, providing a spirited and engaging riding experience. With a top speed of 189 km/h, it was a capable machine for its time. The 5-speed gearbox offers reliable gear changes, and the 24-liter fuel tank ensures a good range between fill-ups. The ergonomics offer a slightly more aggressive riding position compared to the RS models, making it suitable for riders who enjoy a sportier feel. The dual front disc brakes provide decent stopping power, enhancing rider confidence. While wind protection is not explicitly mentioned, the 'S' designation often implies a sporty fairing or windscreen. This model appeals to riders who appreciate classic sport motorcycles with a focus on performance and style. Its air-cooled boxer engine and distinctive styling provide a unique riding experience. The 1978 R 100 S is a great choice for riders seeking a reliable and fun machine for weekend rides and occasional touring.
